Have bought the castle for our basement room in order not ever have a key case or having to search. Unlike a number code, the combination can be easier to remember here; In addition, it is actually more convenient because you do not have to look for any numbers on small cog in the twilight. The white color facilitates the addition and also looks good. The one-hand operation works fine for me, is really no different to solve on the smartphone screen lock. Theoretically the castle even more secure than a Zahlanschloss be, as it allows a combination of up to 99 movements (with more than 8 probably are more impractical) - for me a high level of security was not, however, the main criterion. The manual is indeed very small print, but to understand-my view well being have also seen better movies. Since the castle met all my criteria 100% and this is inexpensive, there's also 5 points from me.
